Explanation of how to use in/out parameters

["Williams,Ed" <EW...@cerner.com>]

Can anyone point me to where in/out parameters have been
discussed/explained, because I seem to be left out?  I've picked up from
that Holders are probably the answer, but I can find nothing on them.

Alternatively, someone please answer the questions I am finding:
The User's Guide (only doc I can find) has a section on Holders in which it
says: "You'll notice that for each data class that Wsdl2java generates,
there is a corresponding "Holder" class".  I don't see any "Holder" classes
generated for my service.
My service has the following method in it:
Widget readWidget(ReadContext rc, WidgetQualifier wq);
I want the ReadContext to be "in/out" and the WidgetQualifier to be "in".
How do you indicate this to the AxisServlet and to the Java2WSDL (?WSDL)
generator?
Any help or info would be greatly appreciated.
